The viral capsid structure determines viral assembly and host specificity during infections. Here, we show cryo-EM structures of = 3 and = 1 PvNV-like particles (PvNV-LPs), crystal structures of the protrusion-domains (P-domains) of PvNV and MrNV, and the crystal structure of the ∆N-ARM-PvNV shell-domain (S-domain) in = 1 subviral particles. The capsid protein of PvNV reveals five domains: the P-domain with a new jelly-roll structure forming cuboid-like spikes; the jelly-roll S-domain with two calcium ions; the linker between the S- and P-domains exhibiting new cross and parallel conformations; the N-arm interacting with nucleotides organized along icosahedral two-fold axes; and a disordered region comprising the basic -terminal arginine-rich motif (N-ARM) interacting with RNA. The N-ARM controls = 3 and = 1 assemblies. Increasing the /-termini flexibility leads to particle polymorphism. Linker flexibility may influence the dimeric-spike arrangement.
